I’ve seen some of that. There have been reports to that effect for some time.
But I think that if it truly spread just from normal talking or breathing the rate of infection would be 90% of the population. But just to be conservative, if truly airborne like that, we could probably safely consider that 70% of our 7.8 billion population that could get it. Which would lead to about 1% of them dying. That’s 546 million people.
I personally don’t think that’s the case. The virus would be much more infectious than it appears to be. As it is it has a lower R0 than the measles. Far lower. The measles is much more airborne.
I do think that if you’re living with someone who is virulent and breathing the same air in an enclosed space or close together like in the same bed, your chances increase.
My biggest concern is walking into a room where someone has sneezed or coughed. If it was a couple seconds before that’s a danger. Especially if the area doesn’t have air circulation.
Healthcare workers are at higher risk because they’re in enclosed spaces with people coughing and sneezing forcefully.
I’m not a doctor or a scientist. But I did ask mine during a phone appointment. Health care officials are really trying to keep people apart because they can’t be counted on to not make mistakes when it comes to hygiene and stopping the spread. But my doctor did ultimately tell me that this spreads the same way a cold or flu does. Asymptomatic people can spread the flu as well.
How Flu Spreads
But unless your next to a person’s face when they breath or talk, there is no evidence you can get it. If an asymptomatic person coughs or sneezes from something else like an allergy or choking on food? Of course they can spread it.
Again, I’m not a doctor or scientist and thus no one should rely on my words. I’m just trying to use logic. And I think the real issue is too many still need convincing of the seriousness.
But you don't know how many people are infected.
A lot of what you said is not, IMO, quite correct.
My doctorate is in anthropology and I have a degree in human biology as well. You do NOT have to be next to a person's face to get (where did you get that?
the flu is not relevant here).
Here's the thing. Coronavirus has very different properties from the flu. Want to see a chart of SOME of them? Here's an article:
Into the Eye of the Cytokine Storm
The shape and physiology of this virus is very very different (hence the word "novel").
Back to the statistics. Iceland found that about 20-40% of its population (depending on locale) had already had CoVid19, despite it being an island. In other studies, 20-50% of regions have already had it -
without symptoms. The shedding period for this virus is
much longer than the flu and its attack on the immune system is getting up there with malaria. There are two strains - one seems much more damaging than the other.
Both will eventually hit nearly every person on the planet - over the next 3-5 years. We urban and suburban dwellers will find it hits us within a year or 18 months (unless you live in a bubble).
Singing spreads it (because breathing deeply and exhaling can communicate it very well). 6 feet is a minimum distance. People have been infected at 12 feet. Even further. There's something called viral load. How much virus is in the person's lungs? If a lot (they are in hospital, etc), they have the ability to propel 12 feet away with a cough and infect their nurse, even if she has a surgical mask. She/he needs to be outside the room. That's a problem, especially since no one goes from their house to a room. Many people will encounter them on their way to the hospital. -with so much virus in them, that their breath can spread it to people 6-10 feet away. God forbid they ever get into an elevator (especially with the so-called blue strain).
3 feet is not enough.
Panting, yawning, coughing, sneezing, sighing spreads it further than 6 feet. 3 feet is not enough (at all) even with a common cold or flu (which can kill many people - surely we should rethink how we interact?)
Sweating, shaking hands, sharing a cup, poor hygiene in table wiping at restaurants, shared towels, all of that increases its spread.
In the end, we'll all get it. Many of us older people will die sooner than we would have.
But comparing it to the flu is somewhat limited. We have flu shots. We have nothing for this. Zilch, nada so far. And it's way more communicable than the flu. And while the flu causes inflammation, this virus attacks certain tissues (lung) and systems (spleen, immune cells) that give it the power to kill a lot of people.
Anyway, I truly hope you find you already have antibodies (wouldn't that be great?) and go on about your life in good health. People who have spiked a fever are probably not contagious if they wait a week after their fever breaks before ending quarantine - but
no one knows about how long the virus lasts and transmits in the asymptomatic. The range in numbers is sobering. Those with mild symptoms transmit for up to 28 days (with an average, perhaps, of about 14).
On surfaces, it can live up to 72 hours (again, elevators are brutal, as are all metal tube thingies like airplanes, buses, subways, taxis), so add the last asymptomatic transmitter plus 72 hours - and yes, you can get it in an elevator or any small space occupied by many people. The Chinese studies show this clearly.
